BOB-SLEIGH.

SPECIFICATION forming part of Letters vPatent No. 526,938, dated October2, 1894. f

Application filed February 23| 1894: Serial No.V 501.2241 (N0 modem Toa/ZZ whom t may concern.-

Be it known that I, SOREN O. PAULSON, a

citizen of the United States, residing at Wah# peton, in the county ofRichland, State of. North Dakota, have invented certain new and usefulImprovementsin Bob-Sleighs, of which the following is a specification,reference belnghad therein tothe accompanyingdrawings.

This invention relates to certain. new and useful improvements in bobsleighs, having for its objects among others to provide a simple andlight sleigh in which each of the runners shall have a movement entirelyindependent of the others, and yet the partsshall be strong and durable.Strength is not sacriflced for the sake of simplicity.l The knee is ofnovel form, being truss-like, and is connected with the bolster in sucha manner as to allow of the necessary movements of the runner. It .formsan extended bearing y'for the bolster to which it is connected foroscillation by clips or analogous means.

- Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined bytheappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, t'orm a part ofthis specification, and in which- Figure l is a perspective view of oneset of runners. Fig. 2 is a vertical longitudinal section through thesame, showing by dotted lines the movement of the runner relatively` tothe bolster. Y

Like letters of reference indicate like parts in both of the views.

As the two sets of runners are alike in all respects I have chosen toshow but one a de-V scription of which will suiice for both. 'The frontand rear runners are designed to be connected in the usual or anyapproved manner, as by a reach. The mode of connecting the two forms nopart of the present invention.

Referring now to the detailsI of the drawings by letter, A designatesthe runner which may be of any desired form, being shown assubstantially circular in cross section although it may assume any othershape.

B is the knee formed of metal and comprising a'horizontal portionY Bpreferably substantially circular in cross section as seen in Fig. 2 andwhich is extended at right angles to the length of the runner, whilefrom opposite endsl thereof branchthe arms b which kmerge into theinclined arms b which are se- /cured to the runner in front and rear ofthe lportion B as shown in both of the views.

C is a brace connected at one end to the knee at the junction of thefront arms b and b and at its other en'd to the front end of the`runner, being preferably bent overthe end of the runner as seen best inFig.2 to form a protection therefor.

D is a substantially U -shaped brace secured at its bend as at d to therunner, and its ends bent to form flanges d which are secured to theinner faces of the arms b near their junction with the arms b', the endof the front arm of this brace being held by the same bolt that securesthe rear end of the brace O as shown in Fig. 2.

A Each knee is secured to the bolster E so as to have free oscillatorymovement. The preferable way of attaching the same is by means of clipsF which embrace the portion B of the knee and are held in the bolster asshown. I employ a clip near each end of the portion B and between saidportion and the under side of the bolster I interpose a wear plate Gwhich is concave upon its under face to receive the portion B of theknee as seen in Fig. 2. By this construction it will be seen that eachrunner is free to oscillate independently of the other, thus allowingthe one to enter declivities while the other is mounting obstructionswithout straining the other parts of the sleigh. The truss-likeconstruction of the knee provides a strong and dura- `ble bearingwithoutdetracting from its lightness or simplicity. The knee proper may beformed of onepiece or of two pieces united at the horizontal portion.The arms b b may incline more or less from a perpendicular as may bedeemed best.

Other modifications in detail may be resorted to without departing fromthe spirit of the invention or sacrificing any ofits advantages.

What I claim as new is- 1. A knee for a sleigh, comprising a transsslIOO

verse horizontal round portion with integralconvergent arms extending inopposite directions therefrom and merging into a single' arm on eachside, and a substantially U- shaped brace secured to the said arms andadapted for connection with the runner, substantially as specified;

2. The combination with a bolster,of runners mounted for independentoscillatory movement and each mounting comprising inclined arms unitingat their upper ends ina horizontal, transverse portion, a substantiallyU-shaped brace between said arms, anda presence of two with the foremostof said arms, substantially brace connecting the front end of the runneras specified.

3. The combination with a. bolster and' a runner, of a knee having ahorizontal portion parallel with the bolster and p ivotallyy held to theunder side thereof and inclined integral convergent arms secured' to therunner and extending in opposite directions from said horizontalportion, a brace between said arms and secured to the runner, a braceconnecting one of`the`arms with the front endof 1 the runner, a wearplate between the under `face of the bolster and the horizontal portionof the knee, and clips securing the said horizontal portion and wearplate to the bolster, substantially as specified.

In testimony whereof I ax my signature in witnesses.
